In CSS, the order of specificity for selectors determines which styles are applied when there are conflicting rules. Here’s a quick breakdown:
1. **ID selectors** (e.g., `#highlight`) have higher specificity than class selectors or tag selectors.
2. **Class selectors** (e.g., `.highlight`) have higher specificity than tag (element) selectors but lower than ID selectors.
3. **Tag (element) selectors** (e.g., `P`) have the lowest specificity.
Now, let's analyze the selectors you provided:
1. `#highlight` - This selects an element with the ID of `highlight` (high specificity).
2. `.highlight` - This selects elements with the class of `highlight` (medium specificity).
3. `P#highlight` - This selects a `<P>` element with the ID of `highlight` (high specificity, but still lower than just `#highlight` by itself).
4. `P.highlight` - This selects a `<P>` element with the class of `highlight` (medium specificity).
5. `P` - This selects all `<P>` elements (low specificity).
Based on specificity, the order from highest to lowest is:
1. `#highlight`
2. `P#highlight`
3. `.highlight`
4. `P.highlight`
5. `P`
Therefore, if there are conflicting styles applied, the styles for `#highlight` would take precedence over the others, followed by `P#highlight`, and so on.
